To examine the influence of the bioethanol additive on the functionality of the fuel vapour restraint systems a suitable test facility is designed. This test facility enables automated long-term tests lasting several weeks. As a result, the adsorption behaviour of the activated carbon filters is examined by the used sensors for multiple ad- and desorption cycles even in case of multicomponent mixtures.en681journal article
